The only compatibility problem will be with the /etc/redhat-release file. If it doesn't work, I can supply a file that does, but I know it works with CentOS 3.3; I've installed it.
I looked at the link and couldn't find anything that said anything about installing on to CentOS 3.x
I'm sorry for being a moron, truly.
But can anyone tell me for sure that they got DA onto CentOS 3.4 which I already have running on my server, and how to buy a DA license since it's not listed in Step 1: Do you meet the system requirements?
